I think you are having a wrong interpretation about this reserved funds because it's not only when there's Dip one will use it to accumulate more Bitcoin NO it can also be use for other obligations outside Bitcoin investment. Secondly, it's not just about having a reserved funds but rather how well can you be able to make good use of it. and investing aggressively is putting oneself into a mess because once you got carried away by a Dip, you are spoiling your investment unknowingly.
Before starting investment it is of course most important to gather knowledge about investment. Because you have invested a lot of hard earned money into Bitcoin to hold it for a long time, but should not let it sink for the slightest reason. So if you want to hold Bitcoin for a long time by following the DCA method in Bitcoin then you must be strategic.
For example, if one wants to sell bitcoin holdings due to lack of family, it would be the worst thing to do, as every person should follow the Bitcoin DCA method with additional funds after meeting the basic needs of his family. Because the Bitcoin DCA method is such an approach that the owner of that holding will surely be successful if followed.
